The 960L Surround Panning Rules

The 960L does not produce a phantom center in 5-
Channel surround modes, and no signal will appear in
both the left and right output channels, no matter where
you set the joystick. In other words, panning across the
front is either between Left and Center or between Right
and Center. For example, an output signal panned to
position 1 in Fig. 4-37 would appear in the left and center
front channels and the left and right surrounds, but would
not appear in the right front.
The 960L has true constant-power panning. As you pan a
sound from one channel to the next, the sum of those
channels' output powers will not change.

Setting Levels

In Input and Output Edit modes, moving any fader
changes its associated signal level. The maximum level
indication is 0.0 dBFS (digital full scale). You can move sev-
eral faders at once. The channel assignments are grouped
to facilitate this.
With outputs set to "0dB," a +4dBu analog input will pro-
duce a -20dBFS signal. This provides 20dB of "headroom."
Optimum S/N is achieved when input levels are kept as
close to digital full scale as practical.

Avoiding Overload

If all eight of the "Overload" LEDs on the LARC2's meter
bridge light (called accumulator overflow), the DSP is
overloading internally. (Certain combinations of parame-
ter settings can cause this.) Reducing input levels may or
may not solve the problem.
If your edits create feedback, press the MUTE MACHINE
key on the LARC2's Numeric Keypad to mute the output of
the current DSP while you solve the problem.
If you're not sure which machine is causing the problem,
press the MUTE ALL key on the Numeric Keypad.
